THE PARTICLE THEORY
CHAPTER 13
PROPERTIES OF SOLIDS
Particles closely packed together in position
Can vibrate but DONT move position
Keep their shape and volume
Solids can't flow or be compressed
PROPERTIES OF STATES OF MATTER
Way of defining how matter behaves
looks,feels and acts
PROPERTIES OF LIQUIDS
Close together but free,move past each other
Stick to each other
Have definite volume
Don't have definite shape
Take shape of container put into
Cant be easily compressed
ARRANGEMENT OF PARTICLES
Common between 3 states of matter (atoms+molecules)
Stay the same,energy and arrangement change
Behave differently in each state of matter
CHANGES OF STATE
Material can change from one state of matter to another
No change in mass,no new substance
WHAT IS MATTER
Anything that occupies space and has mass
cat,book,leaf etc on earth are made up of matter
3 states of matter:
solid
liquid
gas
PROPERTIES OF GASSES
Move free in all directions
Don't keep definite shape,fill container put into
Easy to compress to small volume because their spread out
CONDENSATION
Cooling a gas (removing energy) then changes to liquid
MELTING
When solid is heated to form a liquid (gains energy)
BOILING
When a liquid is heated to form a gas
FREEZING
When a liquid is cooled and turns to a solid
DIFFUSION
Movement of particles from high are of concentration to low
Mainly in gasses and liquids
FOUTH STATE OF MATTER-PLASMA
Similar to gas that can carry it electric charge
particles spread randomly
can conduct electricity unlike gas
